Su Yao, a fan of history in the 21st century, accidentally traveled through time and became the direct descendant of Yinzhen, the fourth prince during the Kangxi period. She thought she would live cautiously in the deep courtyard, but she didn't expect that with her understanding of Qing history and modern thinking, she successfully attracted the attention of the cold-faced fourth master.
The situation of seizing the heir is treacherous. Su Yao cleverly uses modern knowledge to advise the fourth master, from the crisis-ridden palace to the turbulent court. While helping the fourth master recruit talents, they were undermined by the forces of other princes. Su Yao and the fourth master worked together to overcome the difficulties, and their relationship continued to heat up in each crisis.
After ascending to the throne, Su Yao battled wits and courage with the concubines with evil intentions in the harem, and also helped Yong Zheng implement the New Deal. Nian Gengyao became more powerful, and Concubine Nian framed Su Yao to save her brother. Su Yao successfully resolved the crisis with her wisdom and firmly took the throne.
In the end, Su Yao and Yong Zheng joined hands for the rest of their lives. Their love story left a strong mark in the history of the Qing Dynasty, and Su Yao's time travel legend also became a good story that was praised by later generations.
